The decisions made by agricultural households to adjust to climate change(CC)in Iran are not well known.This study is in-tended to investigate the influence of perceptions and socioeconomic,institutional features on farmers'adaptation decisions about CC,which constitute the hypothetical statements of the study.We undertook a survey of 200 farm householders from 31 villages of Ilam Province,situated in the western Iran,as randomly selected.The result discloses that the proposed discriminant model matches the data-set well,with a strong effect size of partial eta-squared(η2=0.38).The analysis further signals that adapters are younger and more well-educated than non-adapters.Adapters are also knowledgeable about CC risks and institutional policy barriers.The adapters have subsidi-ary work,better access to credit,and have good contacts with expansion agents and specialists.The paper concludes that government au-thorities should provide farmers with the enriched capabilities and competencies enabling them to adapt to CC.
